With a recent ConTeXt, the following file (run with "mpost -mem=metafun
test.mp")
% use ConTeXt to typeset labels (needs -mem=metafun option)
verbatimtex %&cont-en
etex
beginfig(100)
% flow arrow
label(btex $\displaystyle\buildrel \rm Flow \over
{=\joinrel=\joinrel\Longrightarrow}$ etex, origin);
endfig;
end
fails with:
! Unable to make mpx file.
l.7 label(btex
$\displaystyle\buildrel \rm Flow \over
Transcript written on fig.log.
The error in mpxerr.log is:
! Illegal unit of measure (pt inserted).

=
<argument> =
\joinrel =\joinrel \Longrightarrow
\buildrel ...mathrel {\mathop {\kern \zerocount #2
}\limits ^{#1}}
l.14 {=\joinrel=\joinrel\Longrightarrow}
$%
It works with ConTeXt 2008.10.31. It fails with ConTeXt 2009.06.04
(with texlive2007 from Debian or with vanilla texlive2008).
